. CREASlNG-WHEEL.

SPECIFICATION forming part of Letters Patent No. 250,745, dated December13, 1881.

Application filed August 30, 1881.

To all whom "it may concern Be it known that I, HENRY F. OSBORNE, acitizen of the United Stat-es, residing in the city of Newark, county ofEssex, and State of New Jersey, have invented certain new and usefulImprovements in Oreasing-Wheels, fully described and represented in thefollowing specification and the accompanyingdrawings, forming a part ofthe same.

My invention relates to an improvement in creasing-wheels forornamenting straps; and it consists in the construction herein describedand claimed.

In the drawings annexed, Figure 1 is a connected view of all the partsof my invention unitedly. Fig. 2 is an edge view, and Fig. 3

a side view, of one of the creasing-disks. Fig.

4 is an edge view, and Fig. 5 a side "iew, of one of the guide-flan ges.Fig. 6 is an end view, and Fig. 7 a side view, of the arbor; and Fig. 8is a side view of the gagecollar. Fig. 9 is an edge view of a series ofgraded gage-collars, the same being fully represented in side view atFig. 8.

The device consists, essentially, of the combination, with an arbor, ofa pair of removable creasing-wheels, a removable gagecollar insertedbetween them, apair of guiding-flanges, and a screw -thread and nut, orequivalent means of clamping the five separate parts upon the arbor.

A is the arbor, (shown provided with ascrewthread upon its exterior, atone end, and a fixed collar, B, at the other end.) A nut, O, is shownfitted to the thread upon the arbor, and serves ito clamp the removablep'arts against the col- D D are guide-flanges 5 E E, the creasingwheels,and F the gage-collar;which serves to keep the wheels E apart thedesired distance. The flanges, wheels, and collar F are bored to fiteasily upon the arbor A, and can thus be removed with facility andreplaced with others. To adjust thefianges to the proper width forguiding the strap over the creasingwheels, the gage-collar F is selectedof such a thickness as to form, with the two creasingwheels, an amountequal to the width of the strap to be creased, a set of the collarsbeing provided with each arbor of gradually-increasing thickness, asshown in Fig. 9. Certain (No model.)

collars of such a set may be dispensed with by combining two collars ofsuitable thickness to produce any larger size required.

In the creasing-wheels heretofore made the double pattern, adapted tocrease the opposite edges of the strap, has been either formed upon asolid cylinder of metal, and therefore adapt ed to operate upon only onewidth of strap, or upon two disks not adapted to exchange with others,in combination with the same guideflanges and collar F. My constructiontherefore affords two advantages not possessed by any other-that thecreasingwheels themselves are both removable, and that all the otherparts of the structure are equally well adapted to operate with otherwheels having a different pattern engraved thereon, thus saving theexpense of a new arbor and flanges when a new style of pattern isrequired upon the wheel. This feature may be said to exist in any solidcreasing-wheel, and I do not therefore claim it singly, but incombination with the removable and changeable gage-collar F, by means ofwhich my creasing-wheels are adapted to operate upon straps of variouswidths. Thus in Fig. 1 is shown a plain wave-line engraved upon thecreasing-wheels, which, being each one-quarter of an inch thick andseparated by a gagecollar three eighths of an inch thick, are adjustedto operate upon a strap seven-eighths of an inch wide. By myconstruetion the same creasing-wheels may be operated upon either aWider or narrower strap by merely changing the gage-collar, or thecreasing-wheels may be replaced by others of an ogee pattern, as thatshown in Fig. 2, or by an other desired, thus securing two advantagesnot possessed in common by any other heretofore made.

To keep the flanges D and wheels E from slipping around upon the arbor,a key, a, and

tion of the spindles end affording the means for their convenientremoval and exchange when required. In such case a key inserted in aslot across the spindle could be used to secure the parts in place,washers being inserted to compensate for the variations in thickness ofthe several gagecollars employed.

I am aware that acreasingwheel having thin rings clamped between beveleddisks has been patented, as No. 145,240 in the year 1873, and I do nottherefore claim any such construction, my invention requiring theengraving or shaping of the required creasing-pattern upon the surfaceof the wheels E described herein, and containing neither the beveleddisks nor interposed thin rings which form the essential features of thepatent referred to. My invention further differs from that referred to,in its adaptation to crease straps of difierent widths, which is theprimary object of my invention. The wheel referred to is not thusadapted, nor is it constructed with disks and guide-flanges constructedseparately and kept apart by a gage-collar upon the arbor A, but isarranged in all its parts to act as a'whole, while mineis devised withespecial reference to the use of the guide-flanges and gage collars, incombination with other creasing-wheels of any desired pattern.

Having thus fully described my invention, I claim the same, as follows:

In a creasing-wheel, the combination, with the arborA, provided with thenut G and guideflanges D, of the removable creasing-wheels E E, havingthe pattern out upon their periphery, and the removable and changeablegage-collar F, the latter being inserted between the wheels upon thearbor and clamped with them between theflanges D whenin use,substantially as herein shown and described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

HENRY F. OSBORNE.
